icemanxp300 Posted May 16, 2018 Share Posted May 16, 2018 Ok so nothing like wasting 3 hrs or so trying to mod a ps1 I don't even need as I already have a modded unit. At this point it is purely about principle. I have tried programming numerous times different files. http://www.eurasia.nu/modules.php?name=Downloads&d_op=viewdownload&cid=43 The first I tried was PSX 12F629 package and it says that a 9000 series only uses 3 wires w/ a jumper. I am not sure this pcb is a 9000 series though as the unit says on bottom it is a 7501. Wiring this way will not play any games even original w/that jumper there, I think the wiring diagram may be wrong. I then tried, this mm3 hex dump http://www.maxconsole.com/threads/psx-mm3-hex-dump-for-pic12f629-has-been-released.18321/ This however gives me a configuration verify failed error which I believe is a programming glitch. Using Gq-4x. topic started here about it. http://www.mcumall.com/forum/topic.asp?TOPIC_ID=5513 I have the option of changing the file format I have tried programming the hex file as binary and hex, nothing works. Well original games will play but not burned. Below are the pics of what I am using for wiring. Here is the psx wiring given for the pcb I am using. Here is the mm3 wiring given for the pcb I am using Here is the file format choice I can choose when I load the hex file. ... Quote Link to comment Share on other sites More sharing options...
icemanxp300 Posted May 21, 2018 Author Share Posted May 21, 2018 Ok, so just in case this helps anyone. I decided to try the mm3 again on the pic12f629. This was after many failed attempts LOL. This time I used a different USB port and made sure to have external power on my GQ-4X programmer. I chose hex files and loaded the USA hex file and in the file format mode I chose hex file as well. I then as well lowered the write speed from +2 down to 0. I soldered in a test socket into a 90001 model. I had 2 chips that worked. One was bad and another would program but not work either. At least now I am set-up w/a tester ps1, so I can program and test these and know if they are good or not. The configuration verify failed happened even though the chips worked. That is a programmer error. Quote Link to comment Share on other sites More sharing options...
Bratwurst Posted May 30, 2018 Share Posted May 30, 2018 Just chiming in that I couldn't get any pic to verify writing in hex with a GQ-4X either, but they ultimately did work for the application I wrote them for. 1 Quote Link to comment Share on other sites More sharing options...
